BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Echinacea plant, botanically known as Echinacea hybrida, and hereinafter referred to by the name ‘IFECSSWP’.

The new Echinacea plant is a product of a planned breeding program conducted by the Inventor in Heerhugowaard, The Netherlands. The objective of the breeding program is to develop new vigorous and freely flowering Echinacea plants with large inflorescences with unique and attractive ray floret coloration.

The new Echinacea plant originated from a cross-pollination in July, 2017 in Heerhugowaard, The Netherlands of a proprietary selection of Echinacea hybrida identified as code number 009-15-K010-04, not patented, as the female, or seed, parent with a proprietary selection of Echinacea hybrida identified as code number 009-15-K010-02, not patented, as the male, or pollen, parent. The new Echinacea plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Heerhugowaard, The Netherlands in August, 2018.

Asexual reproduction of the new Echinacea plant by in vitro meristem culture in a controlled environment in Heerhugowaard, The Netherlands since September, 2018 has shown that the unique features of this new Echinacea plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Echinacea have been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘IFECSSWP’. These characteristics in combination distinguish ‘IFECSSWP’ as a new and distinct Echinacea plant:

-   -   1. Upright and relatively compact plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely branching habit.     -   4. Strong flowering stems.     -   5. Numerous and large single-type inflorescences with four         whorls of white-colored ray florets and greenish yellow-colored         receptacle spines.     -   6. Good garden performance.

Plants of the new Echinacea can be compared to plants of the female parent selection. Plants of the new Echinacea differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Echinacea are more compact than plants of         the female parent selection.     -   2. Inflorescences of plants of the new Echinacea have more         whorls of ray florets than inflorescences of plants of the         female parent selection.     -   3. Plants of the new Echinacea and the female parent selection         differ in ray floret color as plants of the new Echinacea have         white-colored ray florets whereas plants of the female parent         selection have light yellow-colored ray florets.

Plants of the new Echinacea can be compared to plants of the male parent selection. Plants of the new Echinacea differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Echinacea are taller than plants of the         male parent selection.     -   2. Inflorescences of plants of the new Echinacea have more         whorls of ray florets than inflorescences of plants of the male         parent selection.     -   3. Plants of the new Echinacea and the male parent selection         differ in ray floret color as plants of the new Echinacea have         white-colored ray florets whereas plants of the male parent         selection have light yellow-colored ray florets.

Plants of the new Echinacea can be compared to plants of Echinacea purpurea ‘Virgin’, disclosed in U.S. Plant Pat. No. 18,684. In side-by-side comparisons, plants of the new Echinacea differ primarily from plants of ‘Virgin’ in the following characteristics:

-   -   1. Plants of the new Echinacea are more compact than plants of         ‘Virgin’.     -   2. Inflorescences of plants of the new Echinacea have more         whorls of ray florets than inflorescences of plants of     -   ‘Virgin’.

Plants of the new Echinacea can also be compared to plants of Echinacea hybrida ‘Meditation White’, disclosed in U.S. Plant Pat. No. 27,015. In side-by-side comparisons, plants of the new Echinacea differ primarily from plants of ‘Meditation White’ in the following characteristics:

-   -   1. Plants of the new Echinacea have larger leaves than plants of         ‘Meditation White’.     -   2. Inflorescences of plants of the new Echinacea have more         whorls of ray florets than inflorescences of plants of         ‘Meditation White’.
